Tiger Woods has scheduled an announcement on Golf Channel for Monday morning at 11 a.m. Eastern. He will be on the air with Kelly Tilghman, an anchor for the network.

The topic was not disclosed. Woods has had a disappointing season, re-injuring his left knee at the Masters, withdrawing from the Players Championship after shooting 42 on nine holes, and skipping last month’s U.S. Open and this week’s British Open.

Dr. Anthony Galea, a Canadian sports doctor who has worked with Woods in the past, pleaded guilty in federal court Wednesday to bringing unapproved drugs into the U.S.
